My First IAC Experience in the “City of Space” by Adrian Salces (BIRDS-2)

Inspired by this year’s theme #InvolvingEveryone, theInternational Astronautical Congress 2018 has brought more than6000 people in the global space community in Bremen, dubbed asthe “City of Space”. I had the great privilege of participating in thelargest space event in the world to present our work on BIRDS-2Project’s S&F Mission but I experienced much more than that! As afirst-timer, it was exciting to “see” and “hear” about the variouswork and issues that people, organizations and companies are doingin their respective fields. One general observation I had is thatparticipants from almost everywhere in the world utilize space todeal with distinct and common issues – be it economic, political,technological or driven by humanity’s innate desire for “futureexploration” – but regardless of the motivation, everyone had aplatform to share!

Indeed, IAC2018 serves as a learning experience that isbeneficial to my career as a space engineer. Aside from witnessingwonderful presentations, panel discussions, exhibits and evenperformances, I met old and new friends who I can collaborate within future endeavors. Overall, IAC2018 was inspiring, knowledge-enriching, and a great venue for sharing experiences and meetingwith people!

I had the chance to meet Dr. Amalina of UiTM for the first time. She is an Emerging Space Leader awardee.

This was my first time to attend IAC, which is an annual event. It is one of the largest conferences onspace with more than 6,000 participants from around the globe. The participants are not just technicalpeople involved in space but rather consists of lawyers, entrepreneurs, musicians and so on. It is goodopportunity to meet many people at one place.To mention two highlights of IAC2018: 1) Plenary event on “Gravitational Wave Astronomy: Soundsfrom the Dark Side of the Universe.” As predicted by Einstein, a gravitational waves, created when 2Black Holes merge, was detected on ground in 2015. A paper was published on it. Who were authors ofthe paper? 1,004 authors for one paper!2) Listening to astronauts talk. Seven real life astronauts from different countries took a stage to sharetheir ideas. Even the current commander of ISS joined live from space to answer few questions.Advice: There are many parallel sessions. Plan well before hand so as to not miss any session of yourinterest.Repetitive quote at the IAC 2018: Competition is driver. Cooperation is enabler.

It was a great experience to attend IAC2018 in Bremen, Germany. I met and talked with many professionals including professors, researchers, also students that has interest of space science and technology. We gathered and shared the knowledge with each other. I also had the chance to present my research about ionosphere observation in front of so many people, which was an exciting experience! I got feedbacks from the audience that may improve the research as well.

But the things that even more exciting were the lectures and talks that I attended during IAC2018. There were many people talking about going back to the Moon and build a moon base over there. Many also talked about exploration to farther outer space, with Mars as the first step. Listening to all these lectures, not only it broaden my knowledge but also gave me the positive energy to keep pursuing the dream, even though it may sounds too impossible for the others.

I remember in one of the presentations that I attended, the presenter said in the last slide: the process of pursuing something is to get fascinated, then inspired, and motivated. With my background as a student from a developing country, IAC2018 left me a great impression and motivated me to do more especially in space technology. Overall, I encourage another student to gain experience as much as possible that will also support our future career as well.

As BIRDS-3 needed to calibrate the magnetometer used in the satellite we visited Kyushu University Medicinal Botanical Garden in Sasaguri.

International Center for Space Weather Science and Education (ICSWSE), of Kyushu University owns a Helmholtz coil.

We visited this place on 25th of September. Professor Uozumifrom Kyushu University ICSWSE joined to help us with the test. Entrance of the botanical garden Kyushu University

Test Set Up

Checking the alignment of the board before measurement

Magnetometers on the test table

From this room, the north is the X axis of the Helmholtz

coil. If we set the magnetometer properly, in our magnetometer, Y and Z

axis should get some negative value of earth

magnetic field, and X axis should be almost 0.

We installed the MSN board vertically by checking the

spirit level.

Testing ProcedureNo. Operation

Procedure 1

Initial value measurement

Checked the initial value of the magnetometer

Procedure 2

Rough check for magnetometer working

250mG and 500mG was given to X, Y, Z axis and checked

the magnetometer readings.

(The magnetometer readings had some dropping points)

Procedure 3

Find the error of the magnetometer

To check the dropping points the Magnetic Field was

gradually increased and decreased manually

Procedure 4

Measurement after modifying the error

After modifying the program again the magnetic field was

gradually increased and decreased manually to check the

whether there are dropping points.

Procedure 5

Measure the magnetic field value for the

calibration of the Magnetometer

A magnetic field was generated for 60s and the switched

off for 60s. The generated magnetic field was from

60000nT to -60000 nT(±20000nT, ±40000nT, ±60000nT).

Correct the Magnetometer ErrorAt the procedure2 (Rough check for magnetometer working), we found some error of our magnetometer working, by gradually increase/decrease the generated magnetic field.

For each axis value, there is a large gap between ±600 mG. Before we start the calibration test, we needed to correct the error. Also, the value was very noisy, so we also added some function to remove the noise.

±600mG gap ±600mG gap±600mG gap

BIRDS Project Newsletter – No. 33 Page 57 of 66

Correct the Magnetometer ErrorAfter correct the gap error and noise problem, we checked the gradually increase/decrease the magnetic field again (test procedure 4).

As you can see from this result, the ±600mG gap had been removed. Actually, some noise still there, but they are the tolerance for this test. Also, as mentioned on the previous page, X axis value is almost 0mG. Now we were ready to start the proper calibration test (procedure 5).

Conclusion

• In this magnetometer test, we could get the linearity in the graph of the theoretical value and measured value.

• Currently, our magnetometer meets the requirements of satellite stabilization mission.

• As a future task, we will execute some test about whole ADCS system which includes this magnetometer, gyro sensor, GPS, and magnetorquer by using some test equipment in our laboratory.

We, the authors, wish to gratefully acknowledge the huge amount of assistance from Prof. Uozumi of Kyushu University.

“Launching of Nepal’s First Satellite in Nepalese Media”

On behalf of Government of Nepal, Nepal Academy of Science and Technology (NAST) and Kyushu Institute ofTechnology (Kyutech) Japan had signed the MOU to launch the first Nano-Satellite of Nepal in Space. Besides this,Kyushu Institute of Technology has been supporting NAST time and again both technically and academically inorder to gain knowledge on Nano Satellite technologies. As this is the first time Nepal is launching its first Nano-satellite, various national and local medias such as televisions, newspapers, FM Radios, online portals, etc. aretaking interest in covering up the news on BIRDS-3 project as well as Nepal's first Nano-Satellite. Curiosity on thistopic amongst the youngsters, technical experts, students of Science and Technology is growing at a greater pace.Along with this, medias has been supporting to this project highlighting and publicizing this Birds-3 project as wellas Nepal's first Nano-satellite. Dr. Buddhi Ratna Khadge, Secretary of NAST, in an interview quoted to establish aGround Station along with Space Centre by this year with the cost of seed money of NPR. 2 crores for hardwareand launching cost to Kyutech. Similarly, Dr. Rabindra Pd. Dhakal, Chief of Faculty of Technology, NAST, marked toprovide opportunity for the Engineers and Space related students in the field of research, development of satellitein the home country as well as its application therein encouraging the youth. The former Vice-chancellor of NAST,Prof. Dr. Jiba Raj Pokharel has initiated this program and had been focusing on its importance and ultimatelydevelops skilled manpower in Nepal. For this, Hari Ram Shrestha has been nominated from NAST to take a stepforward and make a remarkable effort in the field of Nepal's first Nano-satellite.
